Physics — Algebra and Trigonometry
Suggested grades 11–12 · Unit 1: Motion and Momentum
Connect Net Force With a Velocity Change
Analyze supplied motion data and resolve a force into horizontal and vertical components.
▷ 2 teacher video choices: Connect Net Force With a Velocity ChangePreview lesson: Connect Net Force With a Velocity Change
Goal: Calculate acceleration from a finite velocity change and test consistency with a net-force model.
Before this: Rearrange linear equations and use cosine of an angle.
Try together: Together calculate a cart’s velocity change over 3 s if mass is 2 kg and net horizontal force is 4 N, starting at rest.

Physics — Algebra and Trigonometry
Suggested grades 11–12 · Unit 1: Motion and Momentum
Use Signs in a Momentum Account
Calculate a one-dimensional collision and test the boundary required for conservation.
▷ 2 teacher video choices: Use Signs in a Momentum AccountPreview lesson: Use Signs in a Momentum Account
Goal: Predict a combined final velocity and explain the isolated-system assumption.
Before this: Use signed numbers and solve a linear equation.
Try together: Together model two 1 kg carts, one at 4 m/s east and one initially at rest, that stick. Find the final velocity.
